Dislocation transmission mechanical anti-theft lock cylinder and matching key

Abstract

The invention relates to a dislocation transmission mechanical anti-theft lock cylinder and a matching key. The anti-theft lock cylinder comprises a lock cylinder body, the lock cylinder, a fixed ring, a rotary ring, a lock hole, a transmission mechanism and the matching key, wherein each elastic element group consists of four ball elastic elements with the same diameter, a cylindrical elastic element and a spring, two elastic element groups are formed according to different elastic element arraying sequences, and the wave heights or wave trough depths of a tooth profile of the cross matching key are equal to the diameters of the ball elastic elements. The length of the cylindrical elastic element is equal to the thickness of the fixed ring and is integer multiples of the diameters of the ball elastic elements. The lock cylinder is arranged in the fixed ring, the rotary ring is arranged outside the fixed ring, elastic element holes in each elastic element group are axially arrayed on a circumferential cross section at intervals, and the lock cylinder can be rotated for an angle of above 360 degrees along the forward direction and the backward direction. When the matching key is rotated, elastic element holes in the lock cylinder are staggered and separated from the other elastic element holes in the corresponding elastic element group, the rotary ring can then be rotated, furthermore, an unlocking actuating mechanism is driven, and a strong anti-theft function is obtained.

Description

technical field [0001] The invention relates to a mechanical anti-theft lock core and a matching key, in particular to a dislocation transmission type mechanical anti-theft lock core and a matching key. Background technique [0002] A mechanical lock generally consists of a lock body, a lock cylinder, a transmission mechanism, and a dead bolt (bolt). The lock cylinder is the key component, which contains the tumbler group. The movement and movement range of the marbles are determined by the key. Only when the correct key is encountered, the marbles can move to the correct position, and the lock cylinder can rotate or move in other forms, and then drive the transmission mechanism to complete the unlocking action. Because there is a certain connection between the pin and the transmission mechanism, technical opening locks often use this connection in combination with special special tools to move the pin or other related components to the required position, and finally open t...

Problems solved by technology

However, the general precision requirements are high, and the manufacturing difficulty and cost are also high, which may lead to a decrease in mechanical strength. Therefore, some special high-quality materials are used to improve the anti-destructive ability.

There are also locks with strong anti-opening ability, but the unlocking operation process is relatively cumbersome.

But no matter how it changes, the design of most locks has a common feature, that is, before the action of the unlocking mechanism, each pin group (or parts such as blades) and other related unlocking actuators are always in contact with each other or in a certain relationship. , making it possible for technology to open the lock
